Nowadays, people go vegetarian for a variety of reasons. Concern for the environment is a big factor. Health is an even more common reason for vegetarianism.Studies show that vegetarians are much healthier than average people. Vegetarians have much less chances of getting many chronic, degenerative diseases and conditions, such as heart disease, many types of cancer, diabetes, high blood pressure, obesity, kidney stones, gallstones, and diverticular disease. That's partly because, in general, vegetarians are more health-conscious than most people, and are more likely to avoid alcohol, caffeine, and tobacco, and are more likely to exercise regularly.
